Settings for I/O
■ Setting focus
For the analog output, because the measured value is converted to a current of 4 to 20
mA or a voltage of -10 to +10, and is then output, you can freely set the relationship
between the displayed measured value and output value.
Match the settings to suit the connected external device.
Enter the output values for any two current values or voltage values to set the output
range.
Example: When setting 4 mA output (Point 1) for measured value of 0 mm and 20 mA
Separate the two specified points by at least 1% of the rated measuring range of the connected Sensor
Head or 40 Pm.
For example, for a ZW-S40, the two measured points must be separated by at least 12 mm x 0.01 = 0.12
mm as the measuring range is 12 mm (r6 mm).
As an example, here is an explanation of the procedure for setting 4 mA output (Point
1) for measured value of 0 mm and 20 mA output for measured value of 6 mm (Point
2).
